We're dividing 637143 by 40 
We're looking to find how many times 40 goes into 637143.

Advancing to step 1:
40 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 40

Moving on to step 2:
If we divide 63 by 40, we get 1 and a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 40 from 63 and we're left with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 40

Step 3:
237 divided by 40 is 5 with a remainder of 37.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 200 from 237 and we're left with 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 40

Let's proceed to step 4:
40 can be fit into 371 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 159.0
The remainder is 11 after subtracting 360 from 371.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 40

Step 5:
If we divide 114 by 40, we get 2 and a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 1592.0
If we subtract 80 from 114, we get 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 40

Moving on to step 6:
If we divide 343 by 40, we get 8 and a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 15928.0
If we take 320 away from 343, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
230 divided by 40 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 15928.5
Subtracting 200 from 230 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
40 can be fit into 300 7 times, resulting in a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 15928.57
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
If we divide 200 by 40, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15928.575
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
40 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15928.575
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
If we divide 0 by 40, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15928.575
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 15928.575, and the remainder is 0.0.
